I have verified that the public IP for the local server has not changed. Firewall is still forwarding the correct port to the server. Local firewall on the server is not blocking the sync port (local clients wouldn't work).

Settings on the remote client are as follows :

Manage Database Location : Remote IP Address

Manage Connection Information :

Internet (outside a firewall)

http://IP Address

"Prompt for which address to use is greyed out" (would like to be able to enable that)

Any ideas on what I can do to correct this? It fails with the typical, "ACT! is unable to connect to the server. Check to be sure that "accept incoming sync" is enabled...
